mod_cache & mod_rewrite - Apache

Hello,

Let me start off by apologizing if this list doesn't handle questions
like this but I hoped it might seeing as it's about standard Apache modules.

We currently run mod_rewrite successfully on this URL:

/travel/United%20States/t.html
rewrites to:
/c/search2.pl?country=United%20States

We would like to use mod_cache to cache this page, this works fine when
I target the search2.pl URL, but when using the alias ( ie: /travel ) it
always seems to not find the previously cached file. I am assume this is
because it uses the rewritten URL to determine if it should be cached and to
key the cache, then uses the original URL ( ie: /travel ) to see if the
cached object already exists, which it doesn't.

Here is what the logs show on every request to
/travel/United%20States/t.html

[Wed Nov 23 12:06:49 2005] [debug] mod_cache.c(114): incoming request is
asking for a uncached version of /travel/United%20States/t.html, but we know
better and are ignoring it
[Wed Nov 23 12:06:51 2005] [info] disk_cache: Storing URL

[Wed Nov 23 12:06:51 2005] [debug] mod_cache.c(613): cache: Caching url:
/travel/United%20States/t.html

[Wed Nov 23 12:06:51 2005] [debug] mod_disk_cache.c(613): disk_cache: Stored
headers for URL 127.0.0.1/c/search2.pl?country=United States
[Wed Nov 23 12:06:54 2005] [debug] mod_disk_cache.c(684): disk_cache: Body
for URL 127.0.0.1/c/search2.pl?country=United States cached.

As you can see it caches the search2 URL, not the /travel one... As I hit
refresh, it alway prints the above.

If I access the URL at search2.pl ( ie: not using the rewrite ) it works
just fine ( ie: it caches in the first request and pulls from cache the
second time.

Can someone help? Can mod_cache be used on a rewritten URL?

Thanks!

Luc
